Bogomir Ecker (b. 1950 in Maribor, Slovenia), who has shown at documenta and is a member of the Berlin Akademie der Künste, made his name with art in public spaces and context-related sculptures and installations. His works are characterised by an input of scientific points of view. Their themes are sense perception and communication, in particular sight and hearing, and they are frequently technical or apparatus-like in character, without being centred on technology for its own sake. It is rather the medium through whose putative recognition-value the viewer is induced to adopt unaccustomed perspectives.
